They used dark patterns to trick me into signing up. I do not know how anyone can trust them, at all, ever.

The cost is that you can never play Minecraft again

It might be small cost in retrospect.

Nah I sunk many thousands of hours into these accounts; definitely not a small cost. Sure I could get a new account and pay twice for the game I already purchased multiple times - that would’ve ground my gears too

I think the new account would have to be a Microsoft account also, so you wouldn't have even gained anything by not migrating.

Some servers allow joining without a Microsoft account even these days, but probably can't play on any of the servers you regularly play on, if you don't have a Microsoft account.

Including old pre-enshittified versions.

Never play online

That's half the game.
